IMPROVEMENT IN rRINrING-Iasssrs,

TO ALL lWHOM IT MAY CONQERN: v

.Be it known that we, H. M.HALL and GEORGE W. ESPEY,.of Moores Hill, inthe county of Ripley, and

State of Indiana, have inventedY certain new and useful` Improvements inPrinting-Presses; and'wc do hereby declare that the'foll'owing is Vafull, clear, Aand exact description `thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, in which- Figure lirepresents avertical longitudinal section of our printing-press, and i Figure 2 aplan or top view of the saine, a portion oi' the platen being brokenaway to show the 'construction more clearly.

The object of our invention is to provide a handprinting-press, in whichthe downward and upward motion of its hinged platen shall cause thepaper to be placed in proper. position for receiving the impression ofthe types, and remove it therefrom after beingprinted; and to this endour` improvements consist- First, in providing a movable clamp inconnection with the platen,'and operating-.in a manner hereinafter'described, to `present the paper to the type, andv withdraw itwhenprinted, i

` Second',in combining a cam-shaft in thehox with hooks upon the platen,`to effect the pressing-movement.

In the accompanying drawings, A represents a stout box, which forms themain part orbed ofthe press. Partitions, A1, extend across this box,between whiclnthe oor A2 is secured. Above this oor is placed themovable type-bed C, the height of which is regulated by set-screws cpassing through the door. There are four of these screws, but two onlyappear in tig. 1, beinga section'. This arrangement enables the type-bedto be inclined-if necessary. The form D rests, upon the type-bed, andis' held firmly in position after Vthe types' have been set, by theset-scrcwso, which pass through one end of the bos and one of vthepartitiensA, and press against the plate d. Nis an adjustable ink-bed,resting on the *upper part of the box. The box has hinges B2 firmlysecured to it, towhich the platen B is hinged by vpins passing throughleyes in the 'ends of the strap B1. This strap issec'ured to the top' ofthe platen, and has its ends bent downwards at right angles to it, tomoet the hingesiz, as stated.:A Slots, M, one ofwhich shown in'tig. 2,are eut 'through the platen', near its sides, and inthe direction of itslength. A sliding clamp, Gr, upon the bottom of the platen, has its endsturned up to form ear's`,'G, whichA slide in the' slots M. Themovablcj'hw' of this clampis operated by a handle or thumb-piece, g. Thesliding motion of the clamp is`direeted by guides I, which are attachedto its ends, and which slide in` slots K in thc'platen. A rod, It,extends across the topof the platen, and is secured to the ears G. Abent rod, jt', is hooked at its ends to the rod 7;and has a loop,,.fastened toit-s centre. This loop passes through a hole in thestandard L,.\vhich is tnstonc'd to thc box A in such manner as not tointerfere with the movement of the platen B. I-I Il aresprings orfingers, which hold. one. end of the paper to be 4printed in 'contactwith the platen, its opposite endb'eing held between the jaws of theclamp Gr.v These fingers4 are each made in two parts. That portion hywhich the;r are secured to the platen is at right angles with that whichforms thespring.` 'They are secured to the platen by screws passingthrough slots, as shown in iig. 2, which enables the distance betweenthe e'nds of the fingers to 'oe varied to suitdiii'erent widths ofpaper. A strong stra-p of metal, E, is secured Vto the top ofthe-platen, and has the ends bent downwards at-.right angles, andformell into the hooks E. A metallic shaft, I?, extends across the boxA, and turns inthe bearings Fi. It has cam-projectionsf upon it, whichengage with the hooks Eattached to the platen, and has `its ends? formedsquare in section, sons-to reccive the wrench O by which the shaftis-tnrncd. 'l

The operation .of our printing-press is as follows: The type-bed C beingset in proper position by the setscrews the typos arc set up in the formD, which is secured in place by the set-screws c', and the types inkedby a suitable roller. The clamp G boing pivotcd t'o the standard L bythe I-ods/r, and loop h2, the act of raising the hinged platen from thebox causes the clamp G to slidealong the bottom ofthe platen,heingguided'.

bythe blocks I working in 'the slots K, until the ears G have reachedthe ends ,ofthe slots M whichiare farthest fronrthc hinges. The jaws ofthe clampG are then opened by pressing upon V tlr'elhandle or thumbpicceg, and one end of the piece of paper to be printed inserted betweenthem. The 'lowering of the platen 'platen down upon the type, and leavesmp andpaper attached to move back to the' position shown in thedrawings, through the action of the rods, loop, and standard, beforestated,-and the ends of the fingers H hold the end of the paper againstthe platen, andprevent it from bending or doubling. 'lhe shaft F is thenturned, by means of the wrench O, until the camsff catch in the hooks EE', when: further movement of the wrench brings the a clear impressionupon the paper.` .The wrench is thenturned back when the platen israised, the act of which, as before explained, moves The printed pieceis removed, and` a blank upon the box causes the cla until the cams havecleared the hooks, the clamp into proper position for receiving afreshpieee of paper. one inserted, and the operation repeated.

The platen is so hin-ged to the box that it bears equally upon all thetype, and a piece of cloth or velvet is placed upon it where thepaperpresses against it.

Having thus fully explained our improved Aprint.I 1g-press, what weclaim as new, and desire to sec Letters Paten-t, isv i I 1. The movablepaperfclamp' the raising and lowering` of the platen.l

2; The combination ofthe clamp G, and :lingers H, when arranged asdescribed, for the purpose of holding ure by G, when arrangedasdescribed, so as to receive the necessary movement from the paper. 4

3, The combination of the`cam-shaft Fand hooks E', for giving theimpressionto the paper, as set forth.

4. The combination of the clamp G, rod h', and standard L, with theslotted hinged platen B, when arranged and' operating substantially asand for the purpose described.

"In testimony that we claim the foregoing as our own, lwe affix oursignatures in presence of two witnesses.
